HAROLD A. VEBSTER, OF HAVERHILL, MASSACHUSETTS.

NAIL FOR BOOT OR SHOE HEELS.

SPECIFICATION forming part of Letters Patent No. 394,802, dated December 18, 1888.

Application filed February 18, 1888. Serial No. 264,539. (No model.)

To all whom it may concern:

Be it known that I, HAROLD A. \VEBSTER, of the city of Ilaverhill, in the county of Essex and State of Massachusetts, have invented a new and useful Improved Nail, of which the following is a full, clear, and exact description.

This invention relates to a nail more especially designed for use in attaching heels to boots or shoes under the method of attaching heels to boots or shoes forming the subj ect of a separate application, Serial No. 256,061, for Letters Patent of the United States, and with a machine, also forming the subject of a sepa ate application, Serial No. 264,538, for Letters Patent of the l'nited States, for practically carrying out said method.

This improved nail, otherwise of ordinary or other suitable construction, at one end and on its opposite sides is provided with wings which project from the shank in opposite directions and at their inner faces form an acute angle, preferably, sharp with each other.

In the drawings forming part of this specification, Figure 1 is a perspective view of the improved nail of this invention. Fig. 2 is a sectional view of a heel attached to a boot or shoe sole with the improved nails. Fig. 3 is a View of a nail-blank split at one end preparatory to forming a head such as shown, Fig. 1, upon it. Fig. 4. is a cross-section, line I I, Fig. 3.

In the drawings, A represents the shank of the nail, and D its head, and E its point, all integral and solid.

The shank A particularly shown is rectangular in cross-section, Fig. 4, and it has flat opposite sides (L (1 and l) I), and along the opposite sides an it tapers from end to end, and its opposite sides Z) Z) are parallel. The shank from side to side Z) l) is of the same thickness for its whole length, and from side to side a a it is of a tapering thickness from end to end, leaving one end, and the end at which the head D is to be made, larger than its opposite or point E. The larger end of the nail-shankA is split along and for a portion of its length midway, or thereabout, between its opposite tapering sides a a and across its thickness between its parallel sides 1') I), and then opened and spread out, forming on the opposite sides of the shank wings (Z (Z, which project in opposite directions therefrom, and their inner faces form an acute angle, preferably sharpwith each other, so that, forced head first into leather, wood, or other suitable material, or such material forced over themas, for illustrations, as described in the applications aforesaidthey first enter into the material, and then as they continue to enter, and within and by the operation of the material itself upon them, they are spread or opened outwardly from each other, resulting in the end in a clinching of the nail to and within the material simultaneously with its entrance therein or passage therethrongh.

This invention is not to be limited to any particular form of the nail-shank, nor of the nail-point, the invention in no manner relates thereto, nor to the manner in which, nor to the means by which, such parts are produced. Again, while the nail of this invention has been referred to as especially designed for a particular use, and is shown in such use, Fig. 3, it is not intended to limit the inven tion in that particular.

I am aware that it is not new to provide one end of a nail with wings projecting from opposite sides of the shank, as such a nail is shown in Letters Patent of the Unit ed States, dated January 21, 18753, No. 135,051. This I do not claim, broadly; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

The improved nail herein described, provided at one end and on its opposite sides with wings (Z d, which project from the shank in opposite directions and at theirinner faces form an acute angle with each other, substantially as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two si'lbscribing witnesses.
